Games that use Apple II-style artifacting for colors

[Goochman]

BITD I wrote or started a number of games that used redfined character sets(Ultima like) - I started a ship and Island game that had a Cloud element.  As I was playing around I noticed I could get yellow when the pixels were a certain way and also a greenish hue.  This was on my 800 which had blue/brown.  Unfort due to a disk bug I lost a weeks worth of effort and got po'd and didnt finish what would've been my best attempt to date, however I was able to produce white, blue, brown, yellow and green using artifacting.  Yellow and green needed the pixels "just right"

 

I found a picture of an early build.  You can see the green in the trees a bit but with emulation the yellow didnt come out in the lightening bolt.

There were 3 distinct artifacts, only 2 normally used, and artifact near another color or overlay-ed/overlapped with another color allowed for more monitor/eye trickery yielding more colors and shades. Having this discussion with Brian led to the uav supporting them, which he indeed did discover the third artifact while examining a game. You might say the blending is producing artifacts of the artifacting

Think Origin games had a thing for using artifacting. In addition to the Ultima, games I remember Auto Duel (sure I saw US screenshots in colour for this one) and Ogre using a similar technique.
